FREESTYLE CrossTOX®

The column is firmly connected to the arm, therefore sample and solvent can be dosed precisely and at a constant flow rate via the SPE column with positive pressure using a syringe pump. Drying is also carried out via positive pressure with nitrogen.

• Non-stop Policy: If a column becomes blocked, the system detects the overpressure. The column is reset, the system cleans itself automatically and continues with the processing of the next column
• One rack for all types of columns: reusable adapters allow easy changing and mixing of columns of any standard format
• Columns can be moved to any position in the rack area
• Three solvents as standard, upgrade option up to six or even fifteen solvents

Fluidics management is a central component of the robotic system, where precise dosing and control of fluids is essential:

• 10 mL syringe pump for an exact way to dispense solutions and samples in defined quantities with defined flow rates
• 6 freely selectable ports for solvent supply. (Optional upgrade for 15 freely selectable solvents possible)
• N2 valve for drying or evaporation process
• Chemically inert PTFE sample loop for cross-contamination-free work

Double-walled with two independent lines inside the needle. Spray holes are arranged 360° around the needle:

• Spraying solvent into a vial (e.g. for quantitative transfer) or into the vacuum chamber for rinsing and/or cleaning
• Filling into vials closed with septa (e.g. 1 mL vial with insert)
• Sharp tip for piercing a septum without punching out parts of the septum

More than 40 different racks (also temperature-controlled) can be freely combined with the FREESTYLE system.

Maximum flexibility for your applications, just as you need it, also for IAC columns. Only one rack type is needed for all columns in standard formats up to 15 mL. Adaptation is done by adapters. The racks are hooked in easily and transferred to the software with just a few mouse clicks.

The HPLC Direct Injection module is part of the FREESTYLE automated sample preparation system. It allows complete automation from crude extract to chromatogram without any manual intermediate step with excellent results at the same time, by means of online injection into any LC system. Finished samples can be injected into the HPLC by means of sample loop overfilling, whereby the injection volume can be parameterised.

• Complete automation of a routine analytical process
• Processing of sample and standard without manual intermediate step
• Compatible with any HPLC system
• The FREESTYLE system takes over the function of an autosampler - no HPLC autosampler required
• Filling of additional aliquots of sample possible
• 10 coolable positions for standards available (1 mL or 4 mL vials)
• SST sample loops in different sizes possible

Detailed and varied method creation and easy handling in routine are a successful balancing act in the FREESTYLE software.

• One user interface for all FREESTYLE modules.
• Expandability with new modules at the click of a mouse.
• Easy handling through drag & drop.
• Easy creation, reuse and modification of methods.
• Different methods can be mixed in a sequence list.
• Prioritisation of samples possible at any time, even during operation.
